I think sherry because 450 divided by 9 equals 50mph and jose drives 65mph.
Answer
x=12
Step-by-step explanation:
The equations which are true for the values of x given are; x²-4 =0 and 4x²= 16.
<h3>Which equations are true for the values of x?</h3>
The values of x given according to the task content are; x = –2 and x = 2.
By considering equation; x²-4 =0
x² = 4
x = ±2
Also, by considering 4x²= 16;
x² = 16/4 = 4
x = ±4.

Answer:
The time will be 10:42:40 am. = 10:42 am.
Step-by-step explanation:
∵ The time of 10 questions = 10 × 30 = 300 sec. ÷ 60 = 5 min.
∵ The time of 15 questions = 15 × 40 = 600 sec. ÷ 60 = 10 min.
∵ The time of 12 questions = 12 × 2 = 24 min.
∵ The total of the questions = 10 + 15 + 12 = 37
∵ The time of total rests between the questions = 36 × 5 = 180 ÷ 60 = 3 min.
* Note: (The rests time less than the number of questions by 1 because there is no rest after the last question)
∵ The time of sharpens = 2 × 20 = 40 sec. ÷ 60 = min.
∴The total time of the test = 5 + 10 + 24 + 3 + = min.
